Xanthonia, Baly. 

 Here belong two Canadian species. They are small beetles with 

 broad elytra and narrower thorax, as in Adoxns, the upper surface finely 

 pubescent. Dr. Horn separates them thus : — 



Punctures of elytra very confused, with a feeble seriate tendency 

 towards the sides ; elytra usually dull ochreous with piceous spots, 



but sometimes entirely fulvous. .12 in deceiiuiotata, Say. 



Punctures of elytra much finer and arranged in regular series, 

 but slightly confused near the suture ; colour usually pale fulvous, 

 varying through brown or piceous, not spotted. 



. 1 2 in vi/losula, Mels. 



With the last species is united X. Stevensii, Baly. 



Graphops, Lee. 



Small species of more than usually cylindrical form and metallic 



green or coppery colours. The prothorax is rugose, at least on the sides, 



and the elytra pubescent with rather large string composed of distant 



punctures. The two species from the region under consideration aje : — 



Larger (.16 in.). Prothorax punctured, rugose at 



sides pubesceiis, Mels. 



Smaller (.10 in.). Prothorax rugosely punctured over 



the whole disk curtipejinis, Mels. 



MetachroiMa, Lee. 



Contains species which resemble in form the well-known Typophorus, 

 but with post-ocular lobes. Two are found in Eastern Canada. 



Posterior femora simple; thorax densely punctate, somewhat strigose ; 

 usually black, elytra sometimes with a humeral and apical spot 

 (occasionally united along the margin) dull red. Legs pale in 

 Northern specimens. . 12-. 14 in quercatum^ Fabr. 



Posterior femora with a small tooth on lower edge about one-third 

 from the knee ; thorax scarcely at all punctate ; colour variable, 

 from entirely pale through forms with black thorax, suture and 

 elytral spots to those completely black excepting the legs. 

 . 1 3-. 1 8 in dtibiosmn. Say. 



CoLASPis, Fabr. 



Here belongs C. brimnea, Fabr. ( suilla of the Society's List), a pale 

 brownish or yellowish beetle, of oblong-oval form, the elytra costate, the
